b. If the statistics are not zero, the following failures might occur:
−
Interface hardware failure—To test such a failure, connect the cable that is connected
to the local port to a correctly operating port (for example, Port A) with the same
configurations as the local port. If Port A forwards traffic correctly, you can determine
that the hardware of the local port fails. In this event, you must replace the local port with
a correctly operating port.
−
Transceiver module, fiber, or twisted pair failure—To test and resolve such a failure,
replace the transceiver module, fiber, or twisted pair with a good one.
−
Inconsistent configurations—Verify that the configurations (including speed and
duplex mode) of the peer are consistent with the local port. If they are inconsistent,
modify the configurations of the local port.
c. If the issue persists, contact H3C Support.
When you contact H3C Support, provide the following diagnostic information if packet loss
occurs on the chip port with which the interface is associated:
# Execute the debug port mapping slot 1 command in probe view to identify the chip
port with which the interface is associated.

The output shows that Ten-GigabitEthernet 1/0/1 is associated with chip port xe0.
# Execute the bcm slot 1 chip 0 show/c/xe0 command to check the RDBGC and
TDBGC fields for Rx and Tx dropped packet statistics, respectively. The statistics displayed
were generated between the last and the current execution of the command. To view the
change in dropped packet statistics, execute the command twice or more.
